Anti-Reflecting Film Increases Solar Efficiency
A team of researchers at Rensselaer Polytechnic Institute, led by Shawn-Yu Lin has discovered and demonstrated a new method to overcome two major barriers that limit solar energy. Developing a new coating that increases the amount of sunlight captured by the solar panels that allows them to absorb the full solar spectrum from almost any angle, the research team has closer to academia and industry to obtain the high efficiency will make solar energy profitable.
A silicon solar cell is not only absorbed 67.4 so misses almost one third of the sunlight that reaches it. From an economic and efficiency, this light is an untapped opportunity to achieve the proper performance of the solar panels that would lead to widespread adoption of solar energy.
However, during the investigation, after a silicon surface was treated with the new layer created by Lin using nano-engineering, material absorbed 96.21 percent of the sunlight that affected him. This large gain in the absorption was maintained throughout the spectrum of the incident sunlight, from ultraviolet to infrared, through the visible. This technological achievement leads to the solar energy much closer to economic viability.
The new layer of Lin also successfully resolves the challenge of the sides.
Most surfaces can efficiently absorb light within a specific range of angles. That is the case with conventional solar panels. And why some solar panels have a mechanism for industry to move slowly throughout the day so that your panels are perfectly aligned with the position of the sun in the sky. Without this movement system, the panels would not be optimally positioned and therefore absorb less sunlight. However, the counterpart of this increased efficiency is the energy required to drive the automated system, the cost of maintaining this system and the possibility of errors in synchronization or alignment.
The discovery of Lin could return these obsolete mobile solar panels, since the new Anti-layer absorbs the sunlight uniformly from all angles. This me
